Featured Reviews

Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.
Vignesh  K - PeerSpot reviewer
Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.
Steve Bowtell - PeerSpot reviewer
Exceptionally easy to integrate and covers a multitude of cybersecurity issues
The solution's interface appears very simple, but it is very complicated in the back end. So, it removes all the complications that an MSP or an MSSP would normally have. The solution's maintenance depends on whether you run it like an MDR platform where you provide the detection response part for the customer. That would normally be the MSP part. Sometimes, you have customers who are just happy to get an email and tell them what the problem is, and they fix it themselves. If there's no in-house expertise, the MSP or the MSSP can do the maintenance. If there's in-house expertise, it's just a matter of advising them. Overall, I rate the solution an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"Defender helps us prioritize threats across our organization."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"The technical support is good and quick to resolve issues."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Microsoft Defender for Office 365 is a stable solution."
"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
"The solution is exceptionally easy to integrate and covers a multitude of cybersecurity issues."
 

Cons

"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"I'd like some additional features any product can give me to protect our environment in a better way."
"We need to be able to whitelist data at the backend."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"The functionalities could be improved, such as the isolation feature."
"Scalability is lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong."
"The solution's security awareness training and phishing are very United States-focused and don't work very well in Australia."
 

Pricing and Cost Advice

"The product is very expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"The license is expensive because the cost is based on the number of users."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"I know that the product is incredibly expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
